YBa2Cu3O7-x: Discovery
More Information
The first cuprate superconductor, La2-xBaxCuO4, was discovered by Bednorz and Müller in 1986, building on the work of Michel and Raveau on perovskite cuprates. They were awarded the Nobel prize in 1987. A similar compound, using yttrium in place of lanthanum, was found in 1987 to have a critical temperature of 92 K. The discovery of YBa2Cu3O7-δ, or YBCO, resulted in a huge research effort to develop practical YBCO wires and tapes.
